I see that this is documented badly in README.scriptlib2.

You can use the following:

	deps=$(s2_get_attributes $resource_type $resource_name all)
	dep_IP=$(s2_get_attribute_value IP_address $deps)

To retrieve the dependency on an IP_address; this needs cleaning up slightly
as it also means that the resourceQuery gets called twice; it should do the
call once and save both kinds of information returned.
